Widespread Threat:: Severe thunderstorms capable of large hail (golf ball sized or larger), damaging winds, and tornadoes are expected across the central and eastern US from Sunday into Monday.
Population Impact:: Close to half the US population resides in areas potentially affected by these storms over the two-day period.
Timing:: The most significant activity is forecast for Sunday afternoon through Monday evening, with some initial storms possible Saturday night.
Tornado Risk:: A Level 3 out of 5 risk exists Sunday for areas including Nashville, Indianapolis, and St. Louis, with the potential for strong (EF2+) and long-lived tornadoes, particularly after dark.
Nighttime Danger:: Many strong storms are expected overnight Sunday into Monday morning. Nighttime tornadoes are statistically more dangerous. **Why this matters:** Reduced visibility and people being asleep increase the risk associated with nighttime severe weather, making alerts crucial.
Active Season:: 2025 has already seen significantly more tornado reports (around 300) compared to the same period in 2024 (164), even before the typical peak season.
A strong cold front developing in the central US will clash with unseasonably warm, moist air flowing north from the Gulf of Mexico. This temperature contrast, combined with strong upper-level winds (jet stream dynamics) and a developing low-pressure system, will create an environment highly conducive to severe thunderstorm development, including supercells.
Saturday Night: Initial storms may develop from Kansas and Missouri into Iowa, primarily posing a threat of large hail and damaging winds, though an isolated tornado cannot be ruled out. Cities like Wichita and Kansas City should be alert.
Sunday/Sunday Night: This period holds the highest risk (Level 3 of 5) for widespread severe weather. Storms will likely initiate Sunday afternoon from Illinois down to eastern Texas and intensify as they move east through the Mississippi, Ohio, and Tennessee Valleys overnight. Major cities in the Level 3 risk include St. Louis, Indianapolis, Louisville, Memphis, and Nashville. The potential for very large hail, damaging wind gusts, and strong, long-lived tornadoes is significant, especially overnight.
Monday: The severe threat shifts eastward. Storms, potentially ongoing from Sunday night, will track across the Appalachians towards the East Coast. A Level 2 of 5 risk covers a vast area from the Gulf Coast to the Northeast, including cities like New Orleans, Atlanta (early), Charlotte, Raleigh, Washington D.C., and New York City. While damaging winds are the main concern further north, areas from the Mid-Atlantic southward face risks of hail and tornadoes in addition to wind.
The early activity in 2025 follows a trend seen in recent years like 2023 and 2017, which also had high tornado counts early in the year. Being prepared is essential as severe weather season ramps up.
What are the main threats?
Damaging straight-line winds, large hail (potentially larger than golf balls), tornadoes (including strong, EF2+), and localized flash flooding.
When is the greatest risk?
Sunday afternoon through Sunday night presents the highest potential for significant severe weather, including strong tornadoes, across the Mississippi, Ohio, and Tennessee Valleys. The threat continues eastward on Monday.
Why are nighttime storms more dangerous?
Tornadoes occurring at night are harder to see and confirm visually. People are also more likely to be asleep and unaware of warnings, making it crucial to have a reliable way to receive alerts that can wake you up.
Which areas are most affected?
On Sunday, areas from eastern Texas to the southern Great Lakes (including St. Louis, Indianapolis, Nashville). On Monday, the threat shifts to the East Coast, from the Gulf Coast up through the Mid-Atlantic and Northeast (including New Orleans, Atlanta, Charlotte, Washington D.C., NYC).
Residents in the central and eastern US, particularly from the Plains eastward through the Mississippi/Ohio/Tennessee Valleys on Sunday, and across the Southeast, Mid-Atlantic, and Northeast on Monday.
Stay Informed: Monitor forecasts from the National Weather Service and local news. Have multiple ways to receive severe weather warnings (NOAA Weather Radio, reliable weather apps with alerts enabled, local TV/radio).
Have a Plan: Know where your safe place is (basement, storm cellar, or interior room on the lowest floor away from windows). Practice your plan with your family.
Prepare for Nighttime Storms: Ensure your warning devices will wake you up. Keep shoes and a flashlight near your bed.
Secure Outdoor Items: Bring in or tie down items that could be blown around by strong winds.
Check Supplies: Have water, non-perishable food, batteries, and first-aid supplies ready in case of power outages.
This widespread system poses significant risks. Understanding the timing and potential threats for your specific location is key to staying safe.
